Abstract
A magnetic field speed sensor includes one or more magnetic field sensing elements to generate a magnetic field signal indicative of a magnetic field associated with a moveable target and a controller to generate a controller output signal including a plurality of output words, each including a speed pulse and a plurality of data pulses capable of having four different amplitudes. The time between the speed pulses of consecutive output words is indicative of the speed of movement of the target. Each data pulse corresponds to a data bit having a binary value represented by a transition direction of the data pulse and the amplitude of the data pulse. Features include a programmable data pulse width or an adaptively adjustable data pulse width to avoid truncation.
